From 01d3aee86625bd798a5e69afb92517d5530c7ed1 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sat, 17 Aug 2019 16:24:33 +0200 Subject: crypto: sha256 - Make lib/crypto/sha256.c suitable for generic use Before this commit lib/crypto/sha256.c has only been used in the s390 and x86 purgatory code, make it suitable for generic use: * Export interesting symbols * Add -D__DISABLE_EXPORTS to CFLAGS_sha256.o for purgatory builds to avoid the exports for the purgatory builds * Add to lib/crypto/Makefile and crypto/Kconfig Signed-off-by: Hans de Goede Signed-off-by: Herbert Xu --- lib/crypto/Makefile | 3 +++ lib/crypto/sha256.c | 4 ++++ 2 files changed, 7 insertions(+) (limited to 'lib/crypto') diff --git a/lib/crypto/Makefile b/lib/crypto/Makefile index 101a321b8a99..cbe0b6a6450d 100644 --- a/lib/crypto/Makefile +++ b/lib/crypto/Makefile @@ -8,3 +8,6 @@ libarc4-y := arc4.o obj-$(CONFIG_CRYPTO_LIB_DES) += libdes.o libdes-y := des.o + +obj-$(CONFIG_CRYPTO_LIB_SHA256) += libsha256.o +libsha256-y := sha256.o diff --git a/lib/crypto/sha256.c b/lib/crypto/sha256.c index 1458a20d53a5..f2ed75ae6910 100644 --- a/lib/crypto/sha256.c +++ b/lib/crypto/sha256.c @@ -12,6 +12,7 @@ */ #include +#include #include #include #include @@ -218,6 +219,7 @@ int sha256_init(struct sha256_state *sctx) return 0; } +EXPORT_SYMBOL(sha256_init); int sha256_update(struct sha256_state *sctx, const u8 *data, unsigned int len) { @@ -248,6 +250,7 @@ int sha256_update(struct sha256_state *sctx, const u8 *data, unsigned int len) return 0; } +EXPORT_SYMBOL(sha256_update); int sha256_final(struct sha256_state *sctx, u8 *out) { @@ -277,3 +280,4 @@ int sha256_final(struct sha256_state *sctx, u8 *out) return 0; } +EXPORT_SYMBOL(sha256_final); -- cgit v1.2.3-59-g8ed1b
